AA dynamic analysis tool

BA test execution tool

CA debugging tool

DA test management tool

EA configuration management tool

Answer : D

Question 2

Given the Following program IF X <>= ZTHEN Statement 2;ENDMcCabe's Cyclomatic Complexity is :

Answer : B

Question 3

A software component has the code shown below:

Program BiggestA, Biggest: Integer Begin Read A Biggest = 10 While A > 0 Do If A > Biggest Then Biggest = A Endif Read A Enddo End

The component has exit criteria for component testing that include 100% statement coverage. Which of the following test cases will satisfy this criterion?

B10, 0

C10, 5, 0

D10, 11, 0

Answer : D

Question 4

Consider the following pseudo code:

1 Begin 2 Read Time 3 If Time < 12 Then 4 Print(Time, "am") 5 Endif 6 If Time > 12 Then 7 Print(Time 12, "pm") 8 Endif 9 If Time = 12 Then 10 Print (Time, "noon") 11 Endif 12 End

If the test cases Time = 11 and Time = 15 were input, what level of decision coverage would be achieved?

A100% or 6/6

B50% or 3/6

C67% or 4/6

D83% or 5/6

Answer : D

Test case 1 exercises the decision outcomes True, False, False Test case 2 exercises the decision outcomes False, True, False This leaves the True outcome of decision 3 not exercised. Of the 6 possible decision outcomes, 5 have been exercised, so the decision coverage is 5/6 (about 83%).

Question 5

Consider the following pseudo code:

1 Begin 2 Read Time 3 If Time < 12 Then 4 Print(Time, "am") 5 Endif 6 If Time > 12 Then 7 Print(Time 12, "pm") 8 Endif 9 If Time = 12 Then 10 Print (Time, "noon") 11 Endif 12 End

How many test cases are needed to achieve 100 per cent decision coverage?

Answer : C

The three decisions are in sequence and the conditions are all mutually exclusive (if any one is true the others must be false). Hence a test case that makes the first decision true will make the second and third decisions false and so on.

So test case 1 (say Time = 6) would exercise the path True, False, False, test case 2 (say Time = 15) would exercise the path False, True, False. Test case 3 would have to be Time = 12. This combination achieves 100 per cent decision coverage because each decision has been exercised through its true and its false outcomes.

Question 6

A washing machine has three temperature bands for different kinds of fabrics: fragile fabrics are washed at temperatures between 15 and 30 degrees Celsius; normal fabrics are washed at temperatures between 31 and 60 degrees Celsius; heavily soiled and tough fabrics are washed at temperatures between 61 and 100 degrees Celsius.

Which of the following contains only values that are in different equivalence partitions?

A15, 30, 60

B20, 35, 60

C25, 45, 75

D12, 35, 55

Answer : C

Answer (A) includes two values from the lower partition, answer (B) contains two values from the second partition, answer (D) contains one value that is invalid (out of range).

Question 7

A system is designed to accept values of examination marks as follows:

Fail: 0--39 inclusive Pass: 40--59 inclusive Merit: 60--79 inclusive Distinction: 80--100 inclusive

In which of the following sets of values are all values in different equivalence partitions?

A25, 40, 60, 75

B0, 45, 79, 87

C35, 40, 59, 69

D25, 39, 60, 81

Answer : B
